Therefore, UAE reduces extraction time as well as solvent consumption. In addition, UAE can be carried out at a lower temperature, thus avoiding thermal damage to the extracts and minimizing the loss of bioactive compounds. Therefore, it may serve as an effective method for extraction of oil from tea seeds.</p>\u0000 </section>\u0000 </div>","PeriodicalId":15881,"journal":{"name":"Journal of Food Lipids","volume":"16 4","pages":"465-474"},"PeriodicalIF":0.0,"publicationDate":"2009-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1745-4522.2009.01159.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63565900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The moisture, protein, ash and crude fiber contents of seed residues, and the density, refractive index, color, acidity, saponification value, iodine value, unsaponifiable matter content, oxidative state, sterols, tocopherols and fatty acid composition of the extracted oil were determined. The oil contained a high amount of oleic acid (C<sub>18:1</sub>) of up to 74.41% and a high ratio of monounsaturated to saturated fatty acids with moderate oxidative stability.
